BRACELET AND MODE OF ORNAMENTING WIRE THEREFOR.

SPECIFICATION forming part of Letters Patent No. 297,874, dated April 29, 1884:.

Application filed February 25, 1884. (No model.)

- To all whom it may concern-- a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented'certain new and useful Improvements in Bracelets and Mode of Ornamenting Wire therefor, of which the following is a specification, reference being had therein to the accompanying drawings, in which Figure 1 is a side elevation of a bracelet closed embracing my improvement. Fig. 2 is a perspective view of the bracelet open and in condition to be applied'to the wrist. Fig. 3 isa like view of the same form of bracelet with an auxiliary fastening device. Figs. 4, 5, and 6 are details illustrating the mode of ornamenting the wire or stock from which-the bracelet is made or formed. Fig. 7 is a sec tion of the wire with the core removed.

My invention relates to the peculiar method of ornamenting the wire or stock and the formation of a bracelet therefrom, and I will first describe in detail the process of manufacturing or ornamenting the stock, and afterward the construction of a bracelet.

In the drawings like letters of reference in dicate corresponding parts.

A section of the finished wire or stock from which the bracelet is formed is shown in Fig. 6. A represents the wire, and A the softmetal core. In the manufacture of this stock I take a piece or strip of metal proportional to the size of the wire. to be produced, and draw it into the form of a tube by means of the ordinary draw plate or die and bench, in the usual manner. I then fill this tube with a metal or alloy that is softer than the metal composing the tube, or that will fuse at a low degree of heat, or that is readily attacked by acids. Thenext step is to draw the tube, with the core inserted, through dies or plates shaped to provide it with beads or flutes,

which gives it the form shown in Fig. 4.. I prefer to make it quarterfoil in cross-section; but I do not limit myself to the number of beads or flutes, as I sometimes use a lesser or greater number than four, and so far as the method of manufacture is concerned it is immaterial whether two, three, four, or six beads or flutes are formed on the stock. In this fluted wire I next 7 make saw-kerfs c c in the grooves, as shown in Fig. 5, for a purpose which will be hereinafter explained. I then take the wire thus prepared and twist it to form the finished stock, as shown in Fig. 6, as before referred to. It will be seenthat the wire shown in the drawings is quarterfoil in cross-section, giving it externally the appearscribed, I cut off a length sufficient to form a bracelet, A, as shown in Fig. 1. I then remove the core of soft metal or alloy by means of acid or by fusion, and afterward solder to the free ends of the formed bracelet the balls to a or other suitable ornaments.

It is well known that a bracelet made of solid wire, and also of the ordinary forms of tubular wire, possesses but little elasticity, and soon loses what it does possess when subjected to any torsional strain, and, in addition, will buckle or kink when twisted. These objections are overcome by my improvement, as the ends are always held in contact, while at the same time the bracelet retains its original shape. 1 I sometimes use an auxiliary fastening as an additional security. In Fig. 3 I

have shown a small padlock, the hasp of which is passed through suitable loops or eyes,

other articles ofjewelry, and I do not wish to I limit myself in its use.

Heretoi'ore in the manufacture of bracelets of the class to which my invention relates viz., in which the ends of the bracelet are held together by spring action-it was necessary to provide an independent spring, which was generally inclosed in the tubular material of which the bracelet was composed. By my improvement the use of this spring is entirely dispensed with, as the structure of the tubular material I use possesses in itself all the elasticity necessary to keep the ends of the bracelet in a closed position without the use of a separate spring, and I thus not only simplify the structure,but produce a bracelet that is just as effective in use and less liable to get out of repair.

Having thus fully described my improvement, what I claim as new, and desire to se- 20 kerfs in the grooves between the flutes, and 0 afterward twisting it, substantially as described.

In testimony whereof I affiX my signaturein presence of two witnesses.
